4. Product Overview
The VEVOR 4L Water Distiller is engineered for efficient and reliable water purification. Key components and materials ensure high performance and durability.
4.1. Main Components
- Distiller Tank: The main boiling chamber, featuring a 304 stainless steel inner liner.
- Inner Lid: Covers the boiling chamber.
- Cooling Duct: Where steam condenses back into liquid water. Made of 304 stainless steel.
- Nozzle: Dispenses distilled water into the collection bottle.
- Collection Bottle: Made of PBT plastic, designed to collect the distilled water.
- Control Panel: Simple interface for operation.

4.2. Working Principle
The distiller operates by heating tap water to boiling point, converting it into steam. This steam rises, leaving impurities behind. The steam then passes through a cooling coil, where it condenses back into pure liquid water. An activated carbon filter further purifies the water before it is collected.

5. Setup
- Unpack: Carefully remove all components from the packaging.
- Position: Place the distiller on a stable, flat, and heat-resistant surface. Ensure adequate ventilation around the unit.
- Connect Power: Plug the power cord into the distiller's power inlet and then into a grounded electrical outlet.
- Install Collection Bottle: Place the collection bottle directly under the distiller's nozzle.
- Initial Cleaning: Before first use, fill the boiling chamber with water up to the MAX line. Run one distillation cycle without collecting the water to clean the internal components. Discard this first batch of water.

6. Operating Instructions
- Fill Water: Open the distiller lid and fill the stainless steel boiling chamber with tap water. Do not exceed the 'MAX' fill line.
- Close Lid: Securely close the lid. Ensure the activated carbon filter pack is correctly installed in the nozzle.
- Position Collection Bottle: Place the collection bottle under the nozzle.
- Start Distillation: Press the 'RESET' button (or power button, depending on model) to start the distillation process. The unit will begin heating the water.
- Automatic Shut-off: The distiller will automatically shut off when the water in the boiling chamber reaches a low level or when the internal temperature exceeds a safe limit.
- Collection: Once the cycle is complete, allow the unit to cool down before handling. The distilled water will be in the collection bottle.
- Cool Down: For optimal performance and safety, allow the unit to cool for at least 30 minutes between cycles.

7. Maintenance and Cleaning
Regular cleaning and maintenance are crucial for the longevity and efficiency of your distiller.
7.1. Daily Cleaning
- After each use, unplug the unit and allow it to cool completely.
- Discard any remaining water in the boiling chamber.
- Wipe the interior of the boiling chamber with a soft cloth.
- Rinse the collection bottle and lid with clean water.
7.2. Descaling (Weekly/Bi-weekly)
Mineral deposits (limescale) will accumulate in the boiling chamber. Use the provided citric acid powder for descaling.
- Ensure the unit is unplugged and cool.
- Pour approximately 1 liter of warm water into the boiling chamber.
- Add 1-2 tablespoons of citric acid powder.
- Close the lid and let it soak for 30 minutes to 2 hours, or overnight for heavy scale. Do not turn on the distiller during this process.
- After soaking, drain the solution and scrub the interior with a non-abrasive brush or cloth to remove loosened scale.
- Rinse thoroughly with clean water multiple times to remove all citric acid residue.

7.3. Activated Carbon Filter Replacement
The activated carbon filter should be replaced periodically (approximately every 2-3 months or after 30-50 distillation cycles) to maintain water purity.
- Ensure the unit is unplugged and cool.
- Invert the distiller lid and remove the old carbon filter pack from the nozzle.
- Insert a new activated carbon pack into the nozzle.
- Push the nozzle down into the machine until it is securely in place.
